A group of medical professionals and anti-torture activists have compared doctors involved in interrogations at Guantanamo Bay to those who covered up the murder of South African anti-apartheid leader Steve Biko 30 years ago. In a letter published in the medical journal Lancet, 260 signatories write: “The failure of the US regulatory authorities to act is damaging the reputation of US military medicine. No health-care worker in the War on Terror has been charged or convicted of any significant offence despite numerous instances documented.” The letter also says the American Medical Association has failed to respond to their original complaint sent 18 months ago.
